Ingredients

  • 3 pounds russet potatoes
  • 6 tablespoons butter
  • 1 cup sour cream
  • 0.5 cup whole milk
  • 2 cups shredded cheddar cheese
  • 0.5 cup chopped cooked bacon
  • 0.25 cup chopped green onions
  • 1 teaspoon garlic powder
  • 1 teaspoon salt
  • 0.5 teaspoon ground black pepper
  • 0.25 cup parmesan cheese
  • 1 as needed nonstick cooking spray

Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish with nonstick cooking spray.

Step 2

Peel the russet potatoes and cut them into large chunks. Place the potatoes in a large pot of salted water and bring to a boil over high heat. Cook for 15-20 minutes, or until the potatoes are fork-tender.

Step 3

Drain the potatoes and return them to the pot. Add the butter, sour cream, milk, garlic powder, salt, and black pepper. Mash the potatoes until smooth and creamy.

Step 4

Stir in 1 cup of the shredded cheddar cheese, half of the chopped bacon, and half of the chopped green onions until well combined.

Step 5

Spread the mashed potato mixture evenly into the prepared baking dish. Sprinkle the remaining cheddar cheese, cooked bacon, parmesan cheese, and green onions evenly over the top.

Step 6

Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly.

Step 7

Let the casserole cool for 5 minutes before serving. Enjoy!
